METHOD OF PROCESSING NON-SILVER SALT PHOTOSENSITIVE MATERIAL BY WHICH WORKABILITY AND THE LIKE OF WASTE WATER TREATMENT ARE IMPROVED

摘要

PURPOSE:To save the space required for treatment of a processing waste liquid and to enhance workability by separating the waste liquid to solids and water and using the water as diluting water for a development replenishing soln. CONSTITUTION:The waste liquid is separated to the solids and the water and the separated water is utilized as the diluting water for the development replenishing liquid. The solvent contained in the waste liquid is, therefore, circulated and reutilized, by which the water resources are saved and the piping installations for water supply and discharge needed for installation of an automatic developing machine are saved.
